Real-Time Automotive Networking

July 2, 2025

Time-sensitive networking is key to real-time automotive applications

Related To:

Automotive applications need to run in real-time, and these days new vehicles utilize Ethernet to connect sensors, engine control units (ECUs) and advanced driver-assistance systems (ADAS). Time-sensitive networking (TSN) Ethernet connections provide deterministic and low-latency connectiivity required for this type of application.

The following content addresses TSN in an automotive context.

Targeting Automotive and Industrial Apps with 10BASE-T1S

Single-pair Ethernet presents a lighter, lower-cost alternative to RJ-45/CAT5 and 6 that's typically used in computing applications.

What's the Difference Between CAN Bus and Automotive Ethernet?

How does automotive Ethernet build on the legacy of CAN bus to support all of today's advanced automotive features—as well as future developments?

What’s the Difference Between CAN and SPE in the Automotive Industry?

The CAN bus protocol is being phased out of the automotive industry in favor of single-pair Ethernet due to its increased data bandwidth, node efficiency, security, and more.

Secure Automotive Ethernet Switch Adds Lockstep Dual-Core CPU

As software takes over more of the modern car, the systems inside are being held to a higher standard of functional safety.

Meeting the Challenge of Ethernet System Validation

As data becomes as important to modern vehicles as oil and gasoline were in the past, simulators will provide the assurance that every vehicle operates at peak performance.

NXP Outfits Its First 5-nm Automotive SoC with Real-Time CPU Cores

The S32N55 is the initial offering in the S32N family of so-called “super-integration” processors based on the 5-nm process.
